The piker follar rofiicf' ai', fi i'api rate of `niully rigidlysecured tofsaid har by ineens .inight be made in Various ways, theconspeed so that its prongs will engage the cotton which is feddownwardly hy the toothed feed roller 9 pulling .it spurt anddisintegrsting it, so as to free the hulls und other extraneoussubstances roni seid cotton und then cause the cotton to descend. As thecotton thus pulled eport and carried downwardly by the picker. roller,it 'Will/he directed, by s curved guurd plate 2l to combined spirulbester und oo iveyer 22 located iininedieteljwv over the ginning rollerand over the edge of e doctor knife 24 Which` beurs upon said roller.

A curved guard platey extends from the lower edge oit the guard plate 2ltofthe doctor knife, und has secured to it, slotted block 26 udjustablysecured to the lower end of an arm 2T. The upper end of this arm isadjustuhly attached to a her QSnnd noroii u clamping nut 29. Bjmtlieseineens, the guard plete 25 @un be adjusted toward and away from thespiral heater 22 und also inv a vertical direction relatively to 'thedoetor knife.

The peripheral edge of the-spiral bester is provided with teeth 30, andwnile this heurter struction shown in Figs. 5 and 6 is siinple andetiicient. ln theV construction, here shown, the spiral beater comprisese shaft 25a having a spiral groove 25h, and in this spiral groove,twisted disks 25C having toothed peripheral edges, are secured,'-saiddisks abutting edge to edge and forming the spiral flights of theheater-conveyer.

As the` cotton descends itroin the pic-ker roller andy overthe spiralheater, it will be directed to the ginning roller hy a guard plate 3Q,the cotton iinding its Way under the doctor knife bearing upon saidroller, und nully into the flue, through which it is discharged usbefore explained. rEhe seed end other extraneous substances, whichcannot pass under the doctor knife, will caught by the spiralheetereconWeyer which will finally discharge the saine into e 'trough33, from which it will carried by e conn veyer 34.

yl/'hen the seeds pass over the doctor knife, more or less cotton willbe carried with them into the beuter-conveyer, and if the latter werenot provided with teeth, this cotton would nully Find its wey to thedischarge trough The teeth on the beater-con- Teyer will, however,eng-:fige such cotton und present it again to the doctor knife on theginning roller. in fact, the seed will be cominuously carried over undpresented to the doctor knife us long as cotton adheres to said seed,und thus the seed Will, to a great extent, he delinted; ull the cottonentering the machine will he ginned, and the necessity for subjectingthe seed to a subsequent delinting process will be oloviated.A
